I am looking for a simple tool that will let me read the RGB and alpha (A) values of a pixel in an image.
Something like DigitalColor meter but that returns alpha values.
I know this is possible in photoshop but I am looking for a lightweight solution.

Mac OS X has ImageMagick, right?
$ convert Downloads/photo.png -crop 1x1+9+96 txt:-
# ImageMagick pixel enumeration: 1,1,255,rgba
0,0: ( 0, 74,117,251) #004A75FB rgba(0,74,117,0.984314)
The idea is to crop around a specific pixel, then output it to the special txt: format, with an output file name of - which is of course standard output.
You can leave out the the -crop 1x1+X+Y business to just get a listing of all pixels. Also note that you image must have an alpha channel for this to work, otherwise it just won't get included.

thanks but i am looking for a graphic tool. although this looks cool if you are scripting it would be cumbersome otherwise. something like an eyedropper tool would be ideal. – numan – 2012-04-18T21:19:19.080
